New brain-based understanding of mindfulness & meditation strategies for addiction treatment
PRWeb: Mindfulness and meditation have been shown to aid addiction recovery, but which strategy is best? Here Constance Scharff, PhD, Director of Addiction Research at Cliffside Malibu Treatment Center, describes our evolving understanding of the brain-based effects of meditation and mindfulness.
When included in addiction treatment and relapse prevention programs, mindfulness and meditation strategies have been shown to reduce anxiety and help to prevent relapse. But mindfulness and meditation are separate practices and even within meditation, not all styles produce the same results. Which is best?
“Anxiety is universal to the human condition, but addicts experience it to an extreme because they have real problems. Meditation and mindfulness practices can help an addict stop worrying about the past, stop fussing about the future, and can help keep an addict from being caught up in racing thoughts about things they can’t control,” says Constance Scharff, PhD, Director of Addiction Research at Cliffside Malibu Treatment Center.
The more stress and anxiety your brain experiences, the more prone you are to addiction. The same is true of trauma – people who have experienced traumatic events are more likely to abuse substances than people without trauma histories. It’s these two challenges – stress and the influence of traumatic memories – that meditation or mindfulness training are thought to heal in people undergoing addiction treatment.
Scharff describes mindfulness as awareness of the present moment. Within meditation practices, there are two major schools – concentrative meditation in which a person focuses on a thought, a sound or on breathing, and nondirective meditation in which a person gently unfocuses his or her mind and lets thoughts wander.
“What we’re learning is that these practices physically change the way the brain works,” Scharff says.
For example, a new study published in the journal Frontiers in Human Neuroscience used fMRI imaging to look inside the brains of 14 experienced meditators. First, the researchers had people chant a sound while focusing their minds on the meditation syllables. Then researchers had people meditate again, but this time letting their minds wander. They also compared both meditation strategies to rest.
The group from the Norwegian University of Science and Technology found that unfocused meditation led to the most activation of brain areas that deal with the processing of memories and emotions. In fact, unfocused mediation far outperformed both focused meditation and rest in its activation of these areas essential for stress reduction and the successful processing of traumatic experiences.
The authors write that, “These techniques are thought to facilitate mental processing of emotional experiences, thereby contributing to wellness and stress management.”
Likewise, a host of studies show long-term changes in brain structures due to mindfulness and meditation practices, including increased gray matter density, increased neuroplasticity (the brain’s ability to create new synapses), increased activation in brain areas that control attention, and even temperature changes in the brain. New research at the UCLA Mindful Awareness Research Center and elsewhere shows these visible, physical changes are sculpted by the practice of meditation – the more you meditate, the more your brain is changed.
“In addition to long-term changes in the mechanics of the brain, at Cliffside we see another, more short-term benefit – we see addicts making an effort to focus on the things that are happening right now and there’s a calm from making that effort,” Scharff says.
Even outside the ways in which meditation changes the brain, and outside the effects of mindfulness practice on focusing attention on the present, the process of learning to the skill itself may provide a valuable forum in which to practice self change.
“For me, the important part is learning to be non-judgmental,” Scharff says. “A person may only go three seconds before a thought intrudes, and that’s OK. It’s the process of accepting current limitations and learning to fail safely without self-judgment that is beneficial.”
